A reply from Dr. Chris Fraser-Jenkins:
" This is one of the Nephrolepis exaltata (L.) Schott cultivars. It is not
the usual cv. 'Bostoniensis' but it should be fairly easily named from
Benedict or Morton's papers on Nephrolepis cultivars.
A cultivar is a genetic abnormality in a species (forked pinnae,
cristate tips, depauperate pinnules, variegated fronds etc.) which can be
given a cultivar name (new ones must be in English under the Code for
cultivated plants) with a capital letter and inverted commas, once it is
established in more than one garden or living collection. There are many
famous ones in Dryopteris, Polystichum, Athyrium, Polypodium etc. still
cultivated in British gardens (also in Japan and the USA) which are
propagated from original plants, first discovered in the wild as
abnormalities, going back hundreds of years.
Mrs. Andersson-Koto did some work in the 1950s on the genetic ratios in
offspring of some well known cultivars and published some interesting papers
on them. There are quite a lot of photographic books on different cultivars
in various genera.
It is most important NOT to report some cultivar of an exotic species
(N. exaltata is a S. American species, not permanantly established in the
wild in India) as if some new finding for the Indian flora - as some
disreputable authors have done in the past. It is merely a cultivated
exotic species, nothing to do with the Indian flora.
I wonder if my last identification reached you? I identified and
commented on a fern for someone else a couple of weeks ago, under this
eFlora of India heading, but when I tried to post it it did not post as it
said I was not authorised to post it.
Best wishes,
Chris Fraser-Jenkins, Kathmandu. "
Thanks a lot, Dr. Chris Fraser-Jenkins.
